Definitions

  • the invention relates to a device for feeding naturally hard, hot-rolled wires drawn from supply reels to a consumer, e.g. to a multi-point resistance welding machine, and for straightening the wires on their way from the supply reels to the consumer according to the preamble of claim 1.
  • any hot rolled unalloyed or low alloy steel has a pronounced yield point, i.e. a load or stress limit, beyond which the steel expands very much without an additional increase in the load or tension, the stress permitted for the direct use of such steel must be set below the yield point in order to deform the components by reaching the yield point avoid. Cold working not only removes the flow properties of the steel, it also improves its breaking strength.
  • Relatively low alloyed, easily weldable steels can thus be considerably improved in their strength properties.
  • steels pretreated in this way have a smooth, clean surface, which, for example, favors the welding of intersecting wires to welded grids.
  • Such a method of manufacturing gratings, in which all work processes were carried out in succession in one train, is known, for example, from AT-B 214.241.
  • the invention is concerned with the task of designing a device for feeding naturally hard hot-rolled wires to a consumer in such a way that wire breaks are avoided when the wire feed to the straightening device is suddenly interrupted are, or that a proper transfer of the wire emerging from the straightening device at a uniform speed to a discontinuously operating consumer is ensured.
  • This object is achieved according to the invention with a device of the type specified in the introduction by that between the wire loop influencing the conveying speed and the supply reel in front of the take-off device, a known per se, the wire between two wire guides lying on the wire pull axis by means of a rotating rotor rotating at high speed, a radial straightening device and between the rotor straightening device and the chopper as an automatic shutdown device its length variable loop is provided, with this second loop being assigned a scanning device which is capable of switching off at least the take-off device and the rotor straightening device when falling below a predetermined minimum length of the second loop, while the switches associated with the first loop are in addition to the conveying speed of the take-off device and in the same direction they are also capable of influencing the speed of the rotor straightening device.
  • Each wire 1 running from a freely rotatable supply reel 4 is driven by a pair of motorized take-off rollers 2 which grips it with a clamp connection conveyed through a rotor straightening device 3.
  • the straightening device 3 has two wire guides 3a on the wire drawing axis and between them a straightening rotor 3b which deflects the wire several times from the wire drawing axis and rotates with a high number of wires.
  • the wire is deflected from the straight feed direction by a spring-loaded roller 5, which is arranged between two fixed rollers 6 and 7 and is mounted on an arm of a two-armed lever 8 which is rotatably mounted at 11, so that it normally forms a loop-like bulge 12 of a predetermined size.
  • the spring 9 loading the roller 5 must be sufficiently strong to be able to absorb the force required in the normal operation for rotating the reel 4 in the wire 1 without any appreciable reduction in the wire slack between the rollers 6 and 7.
  • a further loop 16 is arranged between each rotor straightening device 3 and the consumer 15, which is only indicated schematically, for example a grid welding machine, which is followed by a simple roller straightening device 17, which only has the task of eliminating permanent deformations resulting from the loop 16, for example.
  • the size of the loop 16 is limited by two switches 18, 19.
  • the switches 18, 19 act on the rotor straightening device 3 in such a way that the drive of the straightening rotor 3b and the drive of the puller roller pair 2 is switched to a higher speed when the switch 18 is actuated, but to a lower speed when the switch 19 is actuated.
  • the switch 18 can also be designed such that if the straightening rotor 3b does not respond to the actuation of the switch, for example because the straightening rotor 3b has been switched off and braked by actuation of the contact 10, the consumer 15 is switched off in a second switch position. On the other hand, the consumer 15 could also be switched off directly from the switch contact 10.
  • a descaling device 20 for example a motor-driven brush set, can be connected upstream of the rotor straightening device 3.
  • each rotor straightening device twists the wire to a certain extent during the straightening process, as a result of which internal stresses are built up in the wire during the straightening process, it may prove expedient to supply a large number of wires to the consumer, at least a number of rotor straightening devices to drive the other direction of rotation in the opposite direction of rotation in order to compensate for the torsional stresses of adjacent wires in a final product, such as a welded grid.
